Greg,
a small Copy and Paste problem,
THIS.GetUNCForDriveLetter(LEFT(lcDriveRoot,2))
wouldn't works in the procedure which is not a part of the class :-)




>>Hi all,
>>
>>I want to set something up on a form that will allow the user to select from a list of valid drives on the system (C:, F:, etc.). I'd like to do this with a listbox or a spinner.
>>
>>How can I determine what the valid drives would be? Once that's determined, how do I get a list of the valid folders on that drive?
>>
>>Thanks!
